Preparation and Analysis Method of Epoxy Silanized Silica Gel
In order to explore the potential application of epoxy silanized silica gel in improving the interfacial properties of composite materials,enhancing the selective adsorption capacity of specific adsorbents,and optimizing the sensitivity and stability of sensors,this study adopted refined chemical modification technology to perform epoxy silanization treatment on silica gel.This treatment aims to introduce active epoxy groups onto the surface of silicone,and further implant diverse functional groups through subsequent epoxy ring opening reactions,greatly expanding the application range of silicone.This study focuses on the preparation and performance analysis of epoxy silanized silica gel,and comprehensively evaluates the physical and chemical properties of modified silica gel through the use of pre-treatment optimization,precise control of reaction conditions,and subsequent purification treatment techniques.Analytical techniques include scanning electron microscopy(SEM),transmission electron microscopy(TEM)to evaluate surface morphology,Fourier transform infrared spectroscopy(FTIR),X-ray photoelectron spectroscopy(XPS)to reveal changes in chemical structure,and thermogravimetric analysis(TGA)to determine material thermal stability.The research results indicate that after optimizing the preparation process,the obtained epoxy silane silica gel exhibits excellent surface morphology,stable chemical composition,and significantly improved thermal stability.This provides a scientific basis for future research on silicone materials.
